Wuxi Qianqiao Strip Steel Co.,Ltd | Updated: Jun 13, 2017

In the market, the commonly used TPE is based on SEBs or SBS as the main base material blending modified materials. How do you distinguish the types of TPE from friends you don't know?

1, hair sticky

As the SBS base material oil absorption capacity is not as SEBs, usually SBS base material TPR than SEBs base material TPE more easily felt sticky. Of course, some low molecular weight sebs or its deck can also cause sticky conditions.

2. Odor

Generally, SBS base material TPR than SEBs base material, the TPE taste is large, generally good TPE can do tasteless;

3, Luster

Usually SBS base material TPR than SEBs base material more shiny, of course, SEBs can also have luster, SBS base material TPR also can do Matt, but also is Matt, SEBs base material TPE feel more delicate, SBS base material TPR feel a bit rough. In addition, the SEBs base material domestic molecular weight distribution is wider, the same molecular weight grade of the base material, made of TPE, imported more Matt delicate.

4. Burning

Generally, the TPR of SBS base material has more smoke than the TPE of SEBs base material, because the SEBs is SBS hydrotreating, the hydrogen content is high, the burning is no smoke, the taste is also small.

5. Processing temperature

Usually SBS base material TPR in 160 around can be hot plastic processing, and sebs base material TPE needs in the 180 around thermoplastic processing, of course, also depends on their molecular weight, if the molecular weight, processing temperature is higher.
